Who,s tried a K&n air filter?

[johnvx220]

Put a K&N filter on my Tdi FR the other day and was disapointed. In the past they always helped. May be only a little with my prevoius diesels but in the case of the FR it seemed worse . I know its a low reving unit compared to petrol but I was hoping a little bit more.

panel filter is it?
if so i wouldn't expect much

Yes, panel type. In previous cars the top end of the rev range was better but in my FR not so. Have taken it out now and put the org. back in.

Doesn't suprise me, Diesel's have to pass more air than petrols anyway [passat 130 was fitted with the 2.5 tdi air filter system as std.] - probabley gain more if you can improve the the air entry too the filter system.

i have had the K&N in since Nov, slight better response on the throt, thats about it, could try the Green range as K&N are a bit oily.
